Applied Energy provides a forum for information on innovation, research, development and demonstration in the areas of energy conversion and conservation, the optimal use of energy resources, analysis and optimization of energy processes, mitigation of environmental pollutants, and sustainable energy systems. The journal publishes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts which bridge the gaps between research, development and implementation. The breadth of coverage ranges from innovative technologies and systems of both fossil and renewable energy to the economic industrial and domestic use of energy with no or minor impact on the environment. Applied Energy is also concerned with the attendant problems of modeling and forecasting, conservation strategies, and the environmental, social and economic impacts of energy policies and usage, including climate change mitigation and other environmental pollution reduction.
The proton exchange membrane (PEM) fuel cell is regarded as the best choice in the next power generation source in recent years due to its high fuel conversion efficiency, low noise, no emissions, and so on. The performance of the PEM fuel cell is dominated by the flow field design. The authors first numerically explore how the changed flow field design by the arrangement pattern of the protrusive gas diffusion layer (GDL) affects the cell performance for a full-scale serpentine channel. The best arrangement pattern of the protrusive GDL is then used to find the optimal combined factors by Taguchi design of experiments. The optimal energy conversion and conservation for this arrangement can upgrade the PEM fuel cell performance about 12% while decreasing pressure drop is approximately 35%. In addition, employing experimental data validates the calculation results of the flow channel design. Both the numerical and the experimental results can contribute to a better comprehension of the flow phenomenon that occurs in the energy process device.
